Cardboard spacers may be two-layer and multi-layer, which depends on their use. Cardboard tubes and brackets are made of recycled paper. Brackets are used to secure cargo during transport. Cardboard cores (tubes) are used for winding of various kinds of materials such as films, fabrics, stretch, etc.
